li) Claims. (Cl. 68-22) This invention relates to laundering machines,and more particularly to a laundering machine which washes, dampdries,and completely dries the fabrics in a single cycle of operation.

It is an object of this invention to provide an improved launderingmachine lof the horizontal axis rotor type which incorporates wringerrolls therewithin upon which the fabrics drop from the peripheral wallof the rotor and pass therethrough during the washing cycle ofoperation.

It is a further object of this invention to provide a laundering machineof the aforementioned type in which the rotor is driven at a lowconstant speed at all times as the fabrics are washed and completelydried in an efficient and rapid manner.

It is a still further object of the invention to provide a launderingmachine of the aforementioned type wherein the wringer rolls are solocated that the fabrics pass therethrough When saturated with thecleansing liquid-and are carried beyond the rolls so as not to passtherethrough after the liquid has been withdrawn and the fabrics are nolonger saturated.

It is a still further object of the invention to `provide a launderingmachine of the aforementioned type in which the fabrics being launderedwill pass through the wringer rolls when saturated with liquid and willpass therebepond when heated from a heat transfer source provided in themachine. A

It is a still further object of the invention to provide a launderingmachine of the aforementioned type which is completely automatic inoperation, one which is relatively inexpensive to manufacture, efficientand durable in operation and construction, easy to repair and maintain,and which requires the operator to handle fabrics only in their drystate.

These and other objects of this invention will become apparent from thefollowing detailed description taken in conjunction with theaccompanying drawings,` in which:

Fig. 5 is a view of structure, similarito that illustrated in Fig. 3,showing another form thereof, and

Fig. 6 is a broken front View of the structure illustrated in Fig. 5.

Heretofore in the art, when constructing, laundering machines of thehorizontal axis type, the vfabrics were carried upwardly by variesdisposed across the peripheral wall on the interior of the rotor fromwhich they tumbled and fell substantially across the diameter of therotor into the water at the bottom thereof, producing awashing action.While this action was not too satisfactory, after the lapse of sucienttime the fabrics became 2,757,530 Patented Aug. 7, 1956 2 cleansed to adegree which was acceptable to the operator.

The present invention employs a similar type of rotor, driven inrotation at a speed which raises the fabrics to a point near the top ofthe rotor at which they drop off into a squeeze mechanism, hereinillustrated as a pair of driven rollers through which the fabrics aredrawn to produce a squeeze operation` thereon which more completelyremoves the dirt from the fabrics and thereby substantially reduces thewashing time. The squeeze mechanism is so located that the fabrics, whensaturated with cleansing iiuid, will drop onto the mechanism and passtherethrough. After the `liquid has been drained from the container andthe fabrics have been squeezed through the rolls, they will be carriedby the rotor beyond the point of saturation drop-off and will dropbeyond the squeeze mechanism and will not pass therethrough dur-v ingthe drying operation. With such an arrangement,y only a small number ofpasses of the fabrics through the: squeeze mechanism will take place andthis will occurv only during the washing and rinsing operations in thelpresence of fluid in the container in which the rotor isdriven. Thecarrying of the fabrics beyond the wringer rolls in the absence ofliquid in the container eliminates; wear on the fabrics which wouldotherwise occur and permits the fabrics to spread out as they aretumbled! to be more readily subjected to the flow of heated moist. airwhich produces the rapid drying. It is contemplated. that the machinewill be employed for performing a complete laundering operation on thefabrics-washing, rinsing, damp-drying and drying, so that the operatorplacing soiled dry clothes within the rotor will remove clean dryclothes therefrom after the laundering operation.

Since twice the cubic contents of a rotor is required for drying thanthat required for Washing, and since a six to eight pound dry load ofsoiled fabrics is usually handled `by laundering machines, to maintin aWashing capacity of from six to eight pound load, it is necessary tosubstantially increase the diameter of the rotor. Since the driers nowon the market have a :capacity of between six and eight pounds offabrics, it might be considered that the present machine is a dryingmachine which has had Washing features incorporated therein rather thana Washing machine converted to a drying machine. This largervolume rotorpermits the squeeze mechanism of the present invention to be oifsetupwardly so as to provide a large access opening for the insertion andremoval of thelfabrics from the front face of the rotor and liquidcontainer. In View of the fact that the squeeze mechanism is employed,there is no necessity for increasing the speed of the rotor sinceextraction takes place through this mechanism rather than through theperipheral wall of the rotor as has been the conventional practice whencentrifugally extracting water from the fabrics.

In Fig. l a laundering machine of the present invention is illustrated,comprising a cabinet 10 having an access door 11, which is hereinillustrated as of D-shape, mounted in the front face thereof. A watertemperature control knob 12 and a cycle control knob 13 are mounted onthe front face of the cabinet above the door and a removable top cover14 is secured on an ornamental bead 15 about the top edge of thecabinet. Adjustable feet 16 are secured to the inner frame of thecabinet by which the machine may be leveled on a oor. In view of thefact that the rotor is run at a low constant speed, there is no unduevibration set up in the rotor and the cabinet and it need not be boltedto the floor or other supporting structure, as has `been the practicein4 centrifuging machines.

`Referring more specifically to Figs. 2, 3 and 4, the cabinet 10 ismounted upon a base 17, preferably of chau nel construction, havingangle-shaped uprights 18 mounted thereon to which side flanges 19 on acontainer 21 are secured, herein illustrated as by bolts 22. Thecontainer has a front face 23, a peripheral wall 24, which may beseparate elements or which may be provided in unit relation as hereinillustrated. The rear edge of the peripheral wall 24 has an outwardlydirected flange 25 to which a rear panel 26 is secured by a channel band27 having a U-shaped sealing element 28 disposed therein. The adjacentedges 29 of the band are drawn together in some suitable manner, hereinillustrated as by bolts 31.

The rear wall 26 has a bearing sleeve 32 secured thereto in which asleeve bearing 33 is rotatably mounted. The sleeve bearing is secured toa spider 34, 'the ends of which are attached to a rotor 35. The oppositeend of the sleeve 33 has a pulley 3:6 secured thereto by suitablemea'ns, herein illustrated as by a setscrew 317. A bearing sleeve 38k ispositioned internally of the sleeve 33, having its inner end secured toa spider 39, the outer ends of which are attached to a plate 41supported in aligned relation to the rear wall 42 of the rotor. Theplate 41 is circular in shape, having its peripheral 'edge flangedrearwardly at 43 in spaced relation to 'a rearwardly extendingcylindrical flange 44 on the rear `wall 42 of the rotor. A flange at theedge of the spider 34 is secured to the flange 4'4 and a ring 45 issecured thereover, for a purpose which will rbe explained hereinafter.

A spider 46 yhas its peripheral edge releasably secured to thev rearwall 26 by nuts 47 which' 'are threaded upon studs 48 which are weldedor otherwise secured to the it and to a channel member 56 disposedtherea'cross for supporting 'a motor 57 by bolts 58V which extendthrough slots-in the plate 55, permitting the motor to 'bef shifted fortightening lthe belts 59-a`n'd 61 which connect the pulley's 62' vand-63 on the Imotor shaft 64 tothe pulleysl 36 and 54 in the conventionalmanner. 65 may be secured to the plate 55, having a bearing in its upper`end for supporting the end 'ofthe shaft `64.

The `front wall 66 of the rotor-'35 has a-'central opening defined by anoutwardly extending flange 67 -on the youter face of which 'a ring 68 issecured which is similar to the `ring '45 on the flange-of the rearwall-of the rotor. The rotor is disposed within the container or ltub24-and is supported therein on pairs of wheels 69 and 71 on'the frontand rear walls of the rotor, respectively. The wheels are Vmounted onshafts supportedonstampings I72, having a flange 73 which is welded itothe inner face of the front and rear Walls of the container or tub 24.The wheels support the `rotor which is driven bythe spider 34 throughthe sleeve 33 and the ypulley`36.

The plate 41 has a bearing 74 in which one `end of a shaft 75 isjournaled for rotation by a pulley 76 which is secured to the shaft. Thepulley is driven lby a belt 77 from the pulley 53, the belt havingaspring-pressed idler pulley 78 disposed in engagement therewithforttenesioning the belt and preventing the 'slippage thereof. The plate 41 isprovided with a slot 79 in which a bearing block 81 is mounted formovement 'toward vand away from the shaft 75. Slot's82 are y'provided oneach side face of the blocki'n which the 'wall portion at 'the "en'ds ofthe slot extends. The slot 79 is wider at the end adjacent tofthe shaft75 to permitthe assembly of :theblock inthe slot. The block'at ythe rearside `of the 'platehas a stud 83 extending therefrom, the outer end ofwhicherttends through anaperture infabrac'ket 84`a`gainst which aspring85 abuts when mounted about the stud 83 for urging theblck-towardtheshaft-7S. YA shaft 8'6 isfjournalediin'vthe block'81,Ltleshathaying iafroll'er Jr87"-se"c1'1red thereto An outboardbracket lil yin engagement with a roller 88 which is secured to theshaft 75. The rollers are preferably made of rubber, plastic or similarmaterial which may have various degrees of hardness depending upon theamount of pressure to be applied to the fabrics passing therebetween.

A plate 91 fits into the top portion of the circular opening 92 in thefront Wall of the container or tub 24 to which it is secured by suitablescrews or bolts. The plate 91 has an arcuate flange 93 spaced from theflange 67 of the rotor,- with the face 94 of the plate disposed inalignment with the front face 66 of the rotor 33. A chordal flange 95defines the upper limits of the access opening 92 to the interior of therotor. A bearing 96 is disposed in the wall 94 for supporting theforward end of the shaft 75, and a bearing block 97 is provided in theslot in the wall to support the forward end of the shaft 86. Thisbearing block is mounted in a slot 79, the same as the block 81, and hasa stud 83, bracket 84 and spring assembled therewith in the same manneras above described.

A washer 98, preferably of nylon or other bearing type of material, isprovided at the ends of the rollers 87 and 88 to vsubstantiallyeliminate all of the friction between the ends of the rollers `and thewalls 41 and 94 `while providing engagement therebetween for preventingthe fabrics from being caught between the roller ends and the inner wallfaces. In this arrangement, the roller 87 is spring pressed against 'theroller 88 at `both ends and may be moved yrelative thereto whileproviding a predetermined pressure to the vfabrics passing therebetween.The peripheral wall 101 i's perforated, being made lof material having aplurality of apertures provided therethrough or made 0f a screenmaterial, as is the conventional practice in drying machines.

The front and rear walls 42 and 66 are spanned by laterally extending,inwardly projecting vanes 102 which engage yand pick up thel fabrics -atthe bottom of the rotor and carry 'them up the left-hand side oftherotor as it is being driven in a clockwise direction. Near-the top ofsuch .movement the fabrics tumble onto the top of the rollers 87 and '88when saturated with cleaning liquid provided in the bottom portion yof`the container 24. Thus, during a washing or cleaning operation in thepresence 'of fluid, the Ifabrics will pass betweenv the rollers and theliquid and dirt particles will be squeezed 'therefrom so 'that thefabrics will be cleaned in a Very short time due to vthesqueezingoperation thereon. The liquid and 'particles squeezed from the fabricswill flow over the rollers fand 'also from the trough formedtherebetween lthrough the 'apertures`79 back vinto the bottom vof thecontainer 24.

The bottom of the container has a sump 103 connected byIasolenoid-operateddrain valve'10`4 to a conduit 105 which isdire'ctlyconnected to a drain or a tank or "conne'cted thereto `through la pump,as is' the conventional practice. When the vdrainy valve is open 'duringthe operation of the rotor, fluid will pass yfrom the contaneri'24 andthe saturated fabrics will continue to pass `between the rollers until asubstantial amount of the lluid'hasbeen squeezed therefrom. Thereafter,the fabrics will be carried'beyond thepoin't'on the peripheral wallfrom'which they:drop, when saturated, to a'fhigher point and therebywill be dropped from the wall along a trajectory which carries theffabrics beyond lthe roller 87 so that they will not pass betweenVltherollers during the drying operation. Thiscarfrying-overof Athefrabrics occurs fortwo 'reasons -first, because the fabrics are lighterwhen not saturated with-theiluii'and second, because Va -slight increasein the rotor speed occurs upon the removal ofthe fluid which caused adrag on the rotor when present during .the washing or cleansingoperation. Thus, unnecessary wear on the"fabri`cs"isavoidedafter -thewashing orl cleansing operationhas occurred. n

uiiiquj'e :system is provided for drying .thefabrcs wl'iicli 4is similar'tdthatillustrated and described in""th"`e' depending application ofWilliam E. Stilwell, Jr., Serial No. 266,050, led January 1l, 1952, andassigned to the assignee of the present invention. This system operateson the principle of recirculating air near its saturation point and at ahigh temperature and maintaining the ternperature and water content atthe high level throughout the drying time. It was found from experimentthat the drying time is reduced more than one-half that required whenambient air is heated, passed through the rotor and discharged into theatmosphere, as has been the common practice in the art.

A blower 106 is mounted on the container 24 or elsewhere within thecabinet 10, driven by a motor 107` which is herein illustrated asdirectly attached to the blower. An intake conduit 108 extends to anintake housing 109 at the front face of the container, a major portionof the recirculated air being drawn therein from an aperture 111 in thefront face of the container. The air is exhausted from the blowerthrough a conduit 112 in which a heating unit 113 is mounted. Thisheating unit has a capacity of substantially 4500 watts when energizedfrom a 230-volt circuit and has a rating of substantially 1500 wattswhen current is supplied from a 115- volt circuit. In eitherarrangement, an accumulator 114 may be provided about the heatingelement 113 for storing heat during the time of the washing or cleansingoperation to be available after the lluid has been drained from thecontainer for heating the saturated fabrics to a high degree oftemperature which aids in the extraction of the fluid therefrom and therapid drying thereof. The heated air is delivered to the container 24through an aperture 115 in the rear wall 26 thereof.

An air duct 116 is connected to the right-hand wall of the sump 103, asillustrated in Fig. 4, which passes along the peripheral wall andforwardly, as illustrated in Fig. 3, to connect into the housing 109through the opening 117 in the rear face thereof. Between 20% and 30% ofthe air passing through the blower 106 is drawn through the duct 116 andmixed with the air drawn from the aperture 111, in the front face of thecontainer 24. The air drawn through the duct 116 passes through a waterspray 118 provided by a spray tube 119 located in a recess in the outerwall of the duct, as illustrated in Fig. 4. The water spray 118condenses a portion of the water in the moisture-laden air and theamount thus removed substantially equals the amount being picked up bythe air, so that the combined air, after being heated, has a substantialainity for the moisture within the fabrics and rotor which is readilypicked up thereby. In this manner, the circulated air is maintained at ahigh temperature with a high moisture content which maintains thefabrics and the interior of the rotor at a high temperature which, asfound from experiment, substantially reduces the drying time. Thepresent laundering machine, therefore, is capable of washing andcompletely drying a load of fabrics in substantially the same time thatlaundering machines known in the art wash and extract water from thefabrics, with the laundered fabrics retaining substantially 100% waterby weight.

It is to be understood that a temperature control water intake valve 121and suitable circuits are provided for timing the admission of water,operating the control valve and the blower and starting and stopping themotor 57 in the conventional manner, so that the complete operatingcycle of washing, rinsing, extracting and completely drying the fabricsmay occur during a single cycle of operation of the machine.

Referring to Fig. 5, another form of the device is illustrated, thatwherein the roller 88 is mounted on the axis of the rotor 122 tosimplify the construction while providing a suicient access openingabout the roller 88. In this arrangement, the forward plate 123 isconstructed as a quadrant to increase the area of the access openingfrom the bottom upwardly at each side of the roller 88. The roller 87 ismounted in a similar manner as herein- 6 above noted, the rear end ofthe shaft 86 being journaled in a slidable block 81 in a slot 79 in aplate 140. The plate is recessed in the rear wall 142 of the rotor andis secured to a sleeve 143. The sleeve 143 is releasably secured to abushing 144 on a spider 145 the arms of which are secured to thecontainer by volts, as in the construction illustrated in Figs. 1 to 4above described. The stud 83, bushing 84 and spring 85 are provided forthe blocks 81 at the front and rear ends of the shaft 86 on the outsideof the plates 123 and 140, as in the construction described above. Theonly difference between the embodiment illustrated in Fig. 5 and that inFigs. 1 to 4 is the disposition of the roller 88 directly on the axis ofthe rotor, with the rotor supported on the bearing on the rear wall ofthe container rather than on the wheels 69 and 71. It is to beunderstood that in either construction the rollers may be mounted inoffcenter relation to the rotor axis or that one of the roller shaftsmay be mounted in alignment therewith. The tubular extension on the rearwall 124 of the container 120 has bearings 125 which engage a sleeve 126extending rearwardly from the rotor 122. The sleeve 126 rotates on thesleeve 143 and a shaft 127 is journaled within the sleeve 143, having aspline 128 engaging spline ways within a sleeve 129 to which the roller88 is secured. The end of the shaft is journaled in a bearing 130secured to the plate 123 and a screw 131 in the end of the shaft 127prevents the shaft from moving rearwardly in the sleeve 129. A pulley132 is connected to the sleeve 126 and a pulley 133 is connected to theend of the shaft 127. The pulleys are driven from belts 134 and 135 frompulleys 136 and 137, respectively. The pulleys are mounted on a shaft138 of a motor 139 which is suitably supported on a plate 141 on thebase frame 17 of the cabinet. An outboard support 149 may be provided onthe end of the shaft 138, the support being attached to the base frame.It will be noted in either type of machine that the roller 88 is drivenat a faster angular speed than the rotor so that the peripheral speed ofthe roller 88 is at least equal to that of the rotor, to make sure thatthe fabrics will not pile up on the rollers as they are deliveredthereto.

Referring again to Figs. 2, 3 and 4, it will be noted that a wiper blade147 is provided in engagement with the surface of the roller 88 acrossthe entire length thereof and that a similar wiper blade 148 is`provided in engagement with the roller 87. The ends of the blades may besupported on the plates 41 and 91 of the structure illustrated in Figs.l to 4`and on the Walls 123 and of the structure illustrated in Figs. 5and 6. The blades may be supported on ngers 146 extending from thefriction washers 98 at the ends of the roller when the washers aresecured against rotation to the plates. ln either case, the blades aremounted in a position to engage and wipe the uid from the rollers andalso to prevent any of the fabrics from adhering to the rollers andbeing carried around thereon as sometimes occurs during wringer rolloperations. It is to be understood that an air circulating system, waterinlet and drain. valves, shaft sealing washers, and other features ofthe machine illustrated in Figs. 1 to 4 may be employed on. the machineillustrated in Figs. 5 and 6.

With either type of machine, a very rapid washing or cleansing operationis performed due to the rapid washing action which occurs when employingrollers or similar types of squeeze mechanisms within the rotor. A rapiddrying of the fabrics occurs after the washing operation due to thecirculation of air at high temperature and moisture content so that thecomplete time cycle of the machine is extremely short for completelylaundering the fabrics. It is to be understood that the machine may beemployed for dry cleaning as well as washing, Idepending upon the typeof fluid provided within the container 24 or 120 and that it may beconstructed asa commercial aswell as a domestic type of machine.
